摘要
A fluidized bed reduction reactor (100) for supplying a reduced iron to a melter-gasifier (1) of a smelting reduction system includes an exhaust gas supply unit (3) for supplying an exhaust gas to a reduction gas supply tube (4) interconnecting the melter-gasifier (1) and fluidized bed reduction furnaces (20, 30, 40) when the pressure of the reduction gas in each fluidized bed reduction furnace radically decreases with the occurrence of pressure peak in the melter-gasifier (1). The fluidized bed reduction reactors further include iron ore flow blockage prevention units for directly bypassing some of the reduction gas from each iron ore discharge tube (33, 43) disposed between the neighboring furnaces to the scrubber (50) when the inner pressure of the melter-gasifier (1) radically increases with the occurrence of pressure peak, and a backup gas supply unit supplying a backup nitrogen gas to the bottom of each fluidized bed reduction furnace when a nozzle of a distribution plate (24, 34, 44) is clogged.
